Angels VS monsters

Today all children may be divided into two categories. The first category includes all children that suffer from the children of the same age. And the second category is made by children who really scuff at others including other children.
Of course those who suffer receive great support among adults and are protected by law. But still children use violence against people who are less strong and less impudent.
The vivid example is the violence in the streets. Some children are suppressed by other children that are either older or simply stronger. All of us heard about cases when children were made to have homosexual oral sex, when children were raped violently by other children and when some of them had such injures that they needed the medical care.
YouTube has thousands of videos that show how children mock at one another fighting, threatening with knife and gun, making each other do sexual perversion, etc. And children suffer from other children being afraid to turn for help because they are afraid that these monsters will get angrier and will be ready to kill the child. This is the real problem.
The majority of parents are afraid to let their children go into the streets because the social children's groups are big power that is able to suppress and damage the child making even good and educated children commit crimes.
